Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and in particular to a 5G pole-mounted circuit breaker. Background Art

[0002] Pole-mounted circuit breakers refer to circuit breakers installed and operated on electric poles. With the rapid development of my country's economy and the continuous increase in power supply, especially the increasing dependence of various types of customers on electricity, in order to improve the power supply reliability of the power grid, pole-mounted circuit breakers are often used in the connection, segmentation and branch lines of the power grid to improve the power supply reliability of the power grid.

[0003] In the related art, the pole-mounted circuit breaker is fixed on the pole by welding a simple bracket made of profile steel structure. Such a bracket has poor stability. When the bracket is loosened due to long-term fatigue or in bad weather, it is difficult for people to find out immediately that the pole-mounted circuit breaker is offset. As the offset accumulates, the pole-mounted circuit breaker will fall and fail to work normally, or even fall to the ground and cause personal safety accidents. Therefore, it is necessary to strengthen the installation stability of the pole-mounted circuit breaker and conduct real-time monitoring at the same time, so as to timely detect and remind relevant staff when the pole-mounted circuit breaker is initially offset.

[0012] The beneficial effects of the present invention are:

[0013] 1. In the present invention, an upper plug rod and a lower plug rod are provided to be inserted into corresponding slots in the main body of the pole-mounted circuit breaker, which not only plays a role of further reinforcement; but also can judge whether the main body of the pole-mounted circuit breaker is offset based on the local offset of the upper plug rod and the lower plug rod.

When the controller receives the feedback pressure value of the first gravity sensor and determines that the column-mounted circuit breaker body is offset, the controller controls the cylinder to push the push rod upward, and the extension section of the outer periphery of the push pin located at the upper end of the push rod touches the primary conductive bead and the secondary conductive bead respectively, so that the circuit of the second gravity sensor and the controller is turned on. At this time, the controller can receive the feedback signal of the second gravity sensor, which not only reduces power consumption, but also protects the accuracy and life of the second gravity sensor.

[0018] 6. In the present invention, a screw rod and a force-applying rod are provided to ensure that the first gravity sensor is in close contact with the first balanced force detection hole, making it more sensitive. BRIEF DESCRIPTION OF THE DRAWINGS
